It has been confirmed that BB4 will start at the end of May with a new-look house and 12 contestants, who are yet to be finalised.
The show is going to return to its original reality format for its nine-week run, without any of last year's gimmicks such as the rich and poor sides.
The producers are looking for ordinary people who will get on well and not play up to the cameras.
The housemates will still have a weekly task to determine their food budget, but the stakes have been increased with the group having to place a minimum 50% bet on the outcome.
We shall still be able to watch the tasks live each Saturday night.
